Sam DeStafano, Scarpa, Felix Alderiso, Joe Waverly, Joe Watts, Frank Schweighs, Lefty Ruggiero, Scarfo
On Sam DeStafano, Scarpa I agree. I don't think Lefty Ruggerio or Joe Watts fit the profile.
I believe Valachi was actually ruled insane before he testified but it was kept secret. Prison doctors examine him
and said so, then later it was revealed many in his family were suicides or committed to mental institutions.
